reexport.c:41:28: error: implicit declaration of function ‘offsetof’ [-Werror=implicit-function-declaration]
   41 |                 addr_len = offsetof(struct sockaddr_un, sun_path) + strlen(addr.sun_path);
      |                            ^~~~~~~~
reexport.c:19:1: note: ‘offsetof’ is defined in header ‘<stddef.h>’; did you forget to ‘#include <stddef.h>’?
   18 | #include "xlog.h"
  +++ |+#include <stddef.h>

reexport.c:41:37: error: expected expression before ‘struct’
   41 |                 addr_len = offsetof(struct sockaddr_un, sun_path) + strlen(addr.sun_path);
      |                                     ^~~~~~
